It is used when the original key has been lost or damaged and you want to restore the keyed function of the switch without replacing the full switch body.\u003c\/p\u003e\u003cp\u003eThis replacement is meant for Blue Sea Systems M-Series battery switch applications, including keyed single-circuit ON-OFF models in the same family. For boats that use a keyed battery disconnect to control access during storage, service, or layup, this small part can save replacing hardware that is otherwise still working.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eSpare locking key for Blue Sea Systems M-Series battery switches\u003c\/li\u003e\n\u003cli\u003eBlack finish that matches black keyed M-Series switch configurations\u003c\/li\u003e\n\u003cli\u003eUseful as a direct replacement when the original locking key is missing or damaged\u003c\/li\u003e\n\u003cli\u003eLets you keep the existing switch in service when only the key needs to be replaced\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis part is for M-Series battery switch setups that use the locking-key style. It is a good match when the switch itself is still in place and functioning, but the keyed insert has been lost, broken, or needs to be kept as a spare on board.\u003c\/p\u003e\u003cp\u003eBefore ordering, match the switch family and keyed style already installed on the boat. That matters most on refits and service work where Blue Sea Systems battery switches may be mounted near the battery bank, inside a locker, or behind a panel and different switch series can look similar at a glance.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis replacement makes sense for owners, yards, and service techs who keep spare electrical parts on hand for routine maintenance. It is especially useful on boats where the battery switch is part of the normal shutdown routine and the keyed function still needs to be available after the original key goes missing.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":52023143923893,"sku":"QBP136633","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1329860_qbp136633.jpg?v=1780191784","url":"https:\/\/www.qualityboatparts.com\/products\/qbp136633","provider":"Quality Boat Parts","version":"1.0","type":"link"}
